What was the extent of ice cover across the UK during the last ice age?
Considerable areas of the physical landscape of the UK were shaped by ice. There is no permanent ice cover in the UK today. However, 20,000 years ago, it was a very different situation when most of the UK was covered by an expanded Arctic ice sheet. The ice was three kilometres thick in places. Large bodies of ice, called glaciers flowed slowly from highlands to lowland areas. The Earth’s climate warmed around 10,000 years ago ending the ice age. The ice melted and retreated, revealing an upland landscape that had been transformed into sharp ridges and steep peaks.
